I made my own pattern for them.But since you are going to use this one.Take a piece of newpaper,and with the fold line on the pattern against the fold line on the paper,scoot the pattern piece down ,until you get the size you need.You don't even have to trace around her lines,just use it as a guide to make it the size you want.I just free hand cut mine,then placed it on my shoulder to see if it was what i wanted.

It's a very simple pattern,so it shouldn't give you any problems.If it does ,post again and we'll help you.

Forgot to say,depending on what fabric you are using,you may need to cut 2, one for the face and one for the lining.
